    Contributor(s):: Hai, Phan Vu, Everts, Henk, Van Tien, Dam, Schonewille, J. Thomas, Hendriks, Wouter H.

    We investigated the effect of Chromonaela odorata ingestion by goat dams during pregnancy on intake of C. odorata by their kids. Alteration of prenatal feed preference may be used to increase feed intake of novel feeds and the transit from outdoor to indoor goat farming in Vietnam. Ten female...

  6. Effect of fasting on self-feeding activity in juvenile sea bass (Dicentrarchus labrax)

    Contributor(s):: Benhaïm, David, Bégout, Marie-Laure, Péan, Samuel, Brisset, Blandine, Leguay, Didier, Chatain, Béatrice

    In various experiments under self-feeding conditions, sea bass groups could be divided into three categories regarding feeder actuation: high, low and zero-triggering fish. In all cases few high-triggering fish were responsible for a high percentage of the feed delivery. A question was raised...

  7. Application of pre-partum feeding and social behaviour in predicting risk of developing metritis in crossbred cows

    Contributor(s):: Patbandha, Tapas Kumar, Mohanty, Tushar Kumar, Layek, Siddhartha Shankar, Kumaresan, Arumugam, Behera, Kumaresh

    The present study reports the pre-partum behaviour of crossbred cows and the behavioural markers to predict the risk of developing post-partum metritis in this species. Dry pregnant crossbred cows (n=20) were observed continuously from 3 weeks before calving till the date of calving using video...

  8. Anthraquinone repellent to reduce take of non-target birds from zinc phosphide rodenticide applications

    Contributor(s):: Werner, Scott J., Tupper, Shelagh K., Pettit, Susan E., Carlson, James C., Linz, George M.

    We evaluated anthraquinone as an avian repellent to reduce take of non-target birds from zinc phosphide rodenticide applications. We observed zero mortalities and no overt signs of zinc phosphide toxicosis among 20 Canada geese (Branta canadensis), 24 horned larks (Eremophila alpestris), and 47...

  9. Personality is associated with feeding behavior and performance in dairy calves

    Contributor(s):: Neave, H. W., Costa, J. H. C., Weary, D. M., von Keyserlingk, M. A. G.

  10. Factors associated with canine resource guarding behaviour in the presence of dogs: A cross-sectional survey of dog owners

    Contributor(s):: Jacobs, J. A., Coe, J. B., Pearl, D. L., Widowski, T. M., Niel, L.

  11. Relationships between feeding behaviour, activity, dominance and feed efficiency in finishing beef steers

    Contributor(s):: Haskell, Marie J., Rooke, John A., Roehe, Rainer, Turner, Simon P., Hyslop, James J., Waterhouse, Anthony, Duthie, Carol-Anne

    To increase the profitability and sustainability of beef production systems, the use of animals with high feed efficiency is preferred. Efficient animals eat less than their peers for the same or better growth. This efficiency can be measured using feed conversion ratios (FCR) and residual feed...

  12. “Hay-bags” and “Slow feeders”: Testing their impact on horse behaviour and welfare

    Contributor(s):: Rochais, C., Henry, S., Hausberger, M.

    The temporal distribution of feeding behaviour is of primary importance in grazing herbivores. Many domestic horses are managed under conditions far removed from the natural environment. For example, restricted access to roughage may induce health problems such as gastric ulceration, but also be...

  13. Feeding response of marble goby (Oxyeleotris marmorata) to organic acids, amino acids, sugars and some classical taste substances

    Contributor(s):: Lim, Leong-Seng, Lai, Sian-Kang Jason, Yong, Annita Seok-Kian, Shapawi, Rossita, Kawamura, Gunzo

    Weaning from live to formulated feeds is a major challenge in the culture of marble goby Oxyeleotris marmorata. It can be solved through dietary supplementation of suitable taste substance as feeding stimulant. However, there is still no information on the suitable feeding stimulant for this...

  14. Feeding, foraging, and feather pecking behaviours in precision-fed and skip-a-day-fed broiler breeder pullets

    Contributor(s):: Girard, Ms Teryn E., Zuidhof, Martin J., Bench, Clover J.

    Broiler breeder chickens are feed-restricted to control growth and maximize chick production. Feed restriction creates welfare concerns as conventional skip-a-day feeding can increase activity levels and oral stereotypies during the rearing period. A precision feeding system has been developed to...

    Contributor(s):: Werner, Scott J., DeLiberto, Shelagh T., Baldwin, Roger A., Witmer, Gary W.

    Effective chemical repellents and repellent application strategies are needed to manage damages caused by wild rodents and rabbits to agricultural resources. For the purpose of comparatively investigating the behavioral response of wild rodents and rabbits to a chemical repellent, we...

  17. Relationships between temperament, feeding behaviour, social interactions, and stress in lambs adapting to a feedlot environment

    Contributor(s):: Rice, Maxine, Jongman, Ellen Caroline, Butler, Kym Lloyd, Hemsworth, Paul Hamilton

    The production of lamb meat is a large and important industry in Australia. Variability and seasonality of the climate and the demand for a consistent product (in terms of weight and age) have led to an increase in the use of feedlot systems for finishing lambs. While most lambs acclimatise to...

  18. Characterisation of Shy-feeding and Feeding lambs in the first week in a feedlot

    Contributor(s):: Rice, Maxine, Jongman, Ellen Caroline, Borg, Samantha, Butler, Kym Lloyd, Hemsworth, Paul Hamilton

    Up to 20% of lambs introduced to feedlots are prone to ‘Shy-feeding’ or inappetence. Factors considered to contribute to the condition of Shy-feeding include: neophobia (environment and concentrated feeds), disease and competition around feeding. However, little is known about the...

  19. Oil sources administered to tambaqui (Colossoma macropomum): growth, body composition and effect of masking organoleptic properties and fasting on diet preference

    Contributor(s):: Pereira, Raquel Tatiane, Paulino, Renan Rosa, de Almeida, Charlle Anderson Lima, Rosa, Priscila Vieira, Orlando, Tamira Maria, Fortes-Silva, Rodrigo

    Tropical fish feeding behaviour and food intake are regulated by a number of environmental factors (e.g.: stress in intensive aquaculture; type or seasonality of food), and also by complex homeostatic mechanisms that involve nutritional requirements. When access to food is not restricted, e.g....

  20. Increased intake and preference for tannin-rich sainfoin (Onobrychis viciifolia) pellets by both parasitized and non-parasitized lambs after a period of conditioning

    Contributor(s):: Costes-Thiré, Morgane, Villalba, Juan J., Hoste, Hervé, Ginane, Cécile

    Ruminants select nutritious feeds and avoid deleterious ones by relying on a learning process. We tested the hypothesis that they may similarly be able to select feeds for their medicinal properties, Le. to self-medicate. Our experimental model was lambs infected with gastrointestinal nematodes...
